6. That 57 is an unweighted number

It is not desirable to have a tiny sample that is weighted up to the proper demographic level because it increases the potential for error by magnifying the effect of individual responses.

But if the Pew Latino sample was 57 (5% of the total) that doesn't mean those responses counted for only 5% of the poll. They are weighted up to match the demographic model.

The unweighted Pew poll sample is 56% female, but nobody mentions that as a flaw. (?) But the female opinion didn't count for 56% of the reported results. It is weighted down to 53%. (Or whatever number Pew uses)

It is possible for a pollster to have a bad demographic model. If Pew had a notion that the electorate is 60% female it would cause nonsensical weighted results.

But the reported unweighted sample sizes do not indicate how much the groups counted in the poll.
